lnien( the cutter-bar may be formed structure thus far described was not invented by me and that I make no claim to any of the described parts, except they may enter into new and useful combination with the paper-cutter to be described. u

As shown in Figs. 1 and 4, the angular front ends 12 of the arms 8, to'wliich the paperguidcs proper are attached, are extended upwardly to facilitate the adjustable attachment of'an angular cutter-bar 13,y extending the full length of 'the platen. This cutterbar has its rear edge sharpened to forni a knife or cutter, and it rests upon the arms 8 with the vertical wall or flange l-i' of the bar iiriposed against the rear sides of the angularl ends 12 of the arms. The flange 14 of th cutter-bar 13 is provided with a pair of longitudinal slots 15 for the reception of headed clamping-screws l16, passed through the arm ends 12 and provided in advance thereof with thumb-nuts 17. constitute retaining devices connecting the paper-guides to the cutter-bar and permitting such guides to be adjusted along the bar an( secured thereto in their adjusted positions. Itis perhaps preferable to adjust both paperguides along-the knife, allowing the latter to remain relatively stationary. Obviously,

however, it is possible to allow one of the guides to remain relatively stationary while the other guide and the knife are moved lengthwise of the platen, or the knife and one of thel guides may remain fixed While the other guide is moved to vary the distance between the two guides. In anycase the paperguides are relatively adjusted to accommod ate a gi ven width. of paper, and the length of the cutting edge exposed Ibetween the guides is simultaneously adjusted to engage the full width of the paper. Byreason ofthis arrangenient of the paper guides and cutter in a' con- .nected organization arranged to swing toward and from the platen it will be seen that when the guides are swung away from .the platen to facilitate the insertion of the paper or the free forward feed thereof the eu tter is simultaneously moved and is restored again to its normal position when the gliides or clamps are swung baclc to engage the web. As will be seen by reference to Fig. 4.-, the paper web or webs -are led upwardly between the rockbar 7 and the cutter-bar, and when it is desired to sever the paper it is simply necessary to draw' il. forward against the cutter ma manner which will be obvious to those skilled in the arl. l

In Fig.v 7 is shown a modified form of the invention, consisting in prolonging the paper-guides rearwardly and in securing the cutter-bar 13 rigidly to the rock-bar 7. In this case the guides and cutter-bar are both carried by a single rocking support--to wit,

the bar 7----and obviously with this arrange- .integral n. il l. lie har 7l. as shown in Fig. 8. 'lhis lat- The screws 16 and nuts 17` ter figure is markedby a further variation of the paper-guiding means, consisting in the provision of guiding and clamping rolls mounted on the arms 8 in lieu of the rearward extension of the paper-guides, as shown i n Fig. 7.

It will be noted that in those forms of the `-invention shown in Figs. 7 and 8 the paper guiding and cutting means, being located at opposite sides of the axis of the bar 7, are moved in opposite directions when the bar is rocked. In Fig. 9 I have shown a further form of the invention wherein I take advantage of this fact to cause the cutter-bar to be presented quite close to the platen, possibly in clamping relation to the paper thereon, when the paper-guides are swung up to release 'the paper. This forni is possessed of some advantages, forthe reason that while the removal of the paper guides'or clamps permits the paper to be drawn forward with greater freedom the cutter-bar acts to clamp the paper with su'llicieiit firmness to insure the proper cutting of the paper when the latter is drawn against the yknife-edge. Furthermore, while the cutter-bar acts as a clamp during the cutting operation it is removed from the platen when the paperguide's are thrown down to their normal positions, and therefore does not interfere with the normal feed of the paper during the writingl operation.

n Fig. 6 is shown a modified form of cutter-bar which may be substituted' for the bar 14 in that form of the invention illustrated in Fig. 4. The variation consists in providing the bar with a single slot a instead of two slots 15, as in that form of bar shown in Fic. `,5.

It is thought that from the foregoing the construction and operation of my attachment will be fully compreliended but I Wish it understood that I reserve the 1ight to effect such changes, modifications, and variations of the illustrated structure as may come' fairly within the scope of the protection prayed.

What I claim is- 1. In a type-writing machine, 'the combination with a platen, of a cutter-bar extending longitudinally of the platen and havin f its cutting edge located at that side. of the bar which is farthest from the printing-line, and apair of margin-guides extendin toward the printing-line of the type-writer om the cutter-bar, said margin-guides being relatively adjustable independently of the cutter-bar to accommodate sheets of different widths and movable in unison toward or from the platen to clamp or release the sheet.

2. In a type-writing machine, the combination with a platen and platen-carriage, of a cutter-bar extending longitudinally ofthe platen and having its cuttin edge located at that sideof the bar which is farthest from the '-Qwwidths, and a support sustaining the cutterprinting-line, a pair of marrrin-guides located between the cutter-har and the rinting-line and relatively adjustable lengt iwise. ot' the platen to aeco'n'nnodate sheets of different bar' and margin-guides in a single organization and movable to withdraw the` margin` guides from the platen or to present said guides thereto.

' 3. in a type-writing machine, tbe combination with a. platen and a cutter-bar disposed lengthwise thereof, of a pair of paperguides connected to the cutter-bar and` relatively adjustable longitudinally thereof.

4. ,ln a type-writing machine, the combination with a platen, ot" a rocking support., and Wiper-guides and a papercutter mounted on the support :to rock therewith, the guidesand eut/ter being oppositely disposed with reference to. theV axis of the su port.

5. ln a type-writing machine, t 1e combination with a platen, of a roek-shaft,` ainl a pair ot' relatively adjustable paper-guides and a paper-cutter c: ried by the roeksshaft.

t3. in a type-writing machine, the eombination with a platen, of a meh-shaft, a pair oi {inwardly-extending paper-guides carried by the rock-shaft, and a-paper-eutter disposed in rear of' the guides.

7V. in. a typewriting machine, thel combi nation with a platen, eta rock-shaft extending longitudinally thereof, a separate cutterbar extending from end to end of the, platen. and connected to the rock-shaft to move therewith, and a pair o'l' relatively adjustable Wiper-guides extending forwardlyT from the cutter-ba' and having operative connection tinrewith. v Y

S. ln a type-writing machine, the eombination with a. platen-carriage, ol a 'platen mounted on the carriage, a rocleshalt carried by the platen-carriage and extending longitudi'nally ot' the platen, and paper guiding and cutting means connected in a single. organization and carried by the rock-shaft.

t). in a type-writing machine., the combination with a platen, ot" a. pair ollv parallel paper-guides, and a paper-cutter, said guides and cutter being relatively adjustable to seeure any desired interval between the guides for the acconnnodatlon ot ditlerent widths of n paper and to adjust the length of the e'tieetive cutting edge.

y 1t). The combination with agt'ront-strike type-writer, of a movable cutter-bar extending longitudinally of the platen above the pranting-pointv and having its cutting edge disposed rearwardly, and a pair of relatively adjustable margin-guides having connection with the cutter-bar for'movement therewith and extended around the front side of the platen.

t1. The combination with a type-writer, of a pa )er guidingr and cutting structure -mountc to rock on an axis disposed longi tudinally ot' the platen, said structure in` cluding paper cutting and guiding means located at the opposite sides of the axis upon which the structure rocks, whereby the cutting means will be moved toward the platen when the guiding means is moved away from the same.

l2. The combination with a type-writer,

ot' a rocking bar disposed longitudinally of the type-writer platen and having a eutter in rear ot its axis, and a )air of margin-guides carried by said har and extended forwardly, whereby the rocking of the bar will move the cutting and guiding means in opposite directions.

13. The combination' with a type-writer,of paj'ierguiding means, papercutting means, and means for'simultaneously moving both the guiding and cutting means to withdraw one oi said means Jfrom the platen and to present the otheroli'said means thereto.

in testimonyr that claim the foregoing as my own I. have hereto allxed my signature in the presence of two witnesses.
